japlac

Years ago maybe 20 I painted trim in one room with 2 of the most expensive paints made, both white, I forget why I used 2 brands, both were stated not to yellow, one has badly. So nobody can say about craplac, use a known name brand.

International is hardly a crap brand. I cant answer the OQ though.

From what I remember, Japlac is some sort of wierd enamal paint. It is

Dunno about the yellowing though. Only paint I've found in our conservatory that hasn't yellowed is the dulux waterbased gloss - horrible to work with though (but much better for my ashtma :))

Japlac is a well known brand going back to at lest the 50's

Japlac is a high gloss lacquer that simulates Asian lacquerwork, specifically JAPanese LACquer.

It is all explained here:

Japlac is a known name brand to those who know anything about the subject. Now crawl back under your rock.

This lot used to do a very tough non yellowing paint, developed mainly to do platform edges on the London Underground I believe.

Absolutely horrible to work with ;)

I tried it but even with synthetic brushes (as recommended by Dulux) the paint film does not merge to form a smooth finish: the brush strokes stay visible.

I tried a roller but found that that caused a diffuse finish rather than a gloss finish.

This is the dilemma: use non-yellowing horrible gloss now and have a horrible finish from day one or use oil based paint and get a horrible finish when it yellows later!

The Dulux help line suggested I tried their new "eco" paint. They said it was water based but with a proper gloss finish. Having burned my fingers with the fast drying gloss, I am scared to make the same mistake twice. Has anyone used this?

Thanks, Stephen.

So would you recommend it for skirting and architrave?

I did search Wikipedia for "japlac" but never thought to look at the "japanning" entry, though IMHO it didn't really say much.

I have heard that lack of UV light accelerates the yellowing of white paint and I remember the underground paint (underground= no uv?) being mentioned here before. IIRC it was expensive though? I will have to ask them.

What type of UV is required to prevent yellowing? Is the yellowing reversible? If you put yellowed paint outdoors or under a sunbed (LOL) or blacklight would it revert back to white?

Thanks, Stephen.

Japlac is a brand of enamel paint that has been on the market since at least 1954. I have no idea how well the white will stand yellowing as I have only used coloured on indoor applications. The colour seems to last well.

I think I still have a tin somewhere: it came with a yellow Viva: long departed.

I've found that yellowing is reversed if the yellowed paint is placed outdoors. I strongly suspect that a sunbed would have the same effect.

not much good if its a door frame :-)
